Abstract
A Single Switch Hybrid Step-up Converter with high voltage gain, which is suitable for renewable energy system, is proposed in this paper. The proposed converter consists of one switched diode-inductor cell and a capacitor. While switching, both are charged in parallel from the input source and discharged in series to the output. In order to obtain extra voltage gain at lower duty cycle, the voltage multiplier cell is integrated with the proposed converter. The main advantages of the converter are high voltage gain, reduced voltage stress, simple structure and low output voltage ripples. The operating principle and steady state theoretical analysis are presented. A 250 W prototype converter is implemented with 12 V input and 120 V output to verify the design and analysis of this converter and it has an efficiency of over 90% in all operations.

Summary
A hefty and viable economic growth in India is engaging a great demand for energy resources. Two or more converters are cascaded together, in which the energy is transferred from one stage to another stage to obtain a high voltage gain Their conduction loss is high and it requires large number of components [6]-[8]. In order to reduce the voltage and current stress in the switch, the coupled inductor based topology has been proposed [12]-[14]. A circuit that combines the switched-capacitor and coupled-inductor methods with boost converter is proposed to achieve high voltage gain [15]-[18]. The voltage gain can be increased by combining voltage multiplier cell with the coupled-inductor boost converter and switched-capacitor boost converter [5] [19] [20]. The operation with switching waveforms, the design considerations, simulated and experimental results are presented in the upcoming sections
